SPORTS PRO Magnetic Titanium Necklace SG160 CO Magnetic Necklace S160 Black X White Black Titanium X White M 47cm [Colantotte] Loop Top

---------------------------------------------------------------------- A lightweight and highly magnetic necklace is now available from the Colantotte SPORTS PRO series. The loop is made of silicone with a diameter of 4 mm and the words "COLANTOTTE SPORTS" are printed on the side of the loop. Silicone is treated with a surface treatment that is comfortable to the touch, reducing stickiness and shine. Inside the silicone, there are three magnets each near the sternocleidomastoid muscle (the muscle that diagonally connects the clavicle from the area below the ear) on the left and right sides of the neck. Eight magnets are placed on the back of the neck. *The sternocleidomastoid muscle is a muscle that is easily stressed during ball sports.
